Earlier versions of the SDO extension required a separate shared
library for the XML DAS. This is now obsolete and any references to
php_sdo_das_xml.dll or
sdo_das_xml.so should be removed from your php.ini.

Unix systems

The three SDO components - the SDO core, the XML DAS and the
Relational DAS - are packaged together with Service Component
Architecture (SCA) into one PECL project, SCA_SDO, so you can
download SCA and all three parts of SDO with the command:

pecl install SCA_SDO

This command will build the SDO shared library as well as
installing the PHP files that make up SCA and the SDO
Relational DAS.

If you want to use the latest beta version, then instead run:

pecl install SCA_SDO-beta

The pecl command automatically installs the SDO
module into your PHP extensions directory. To enable the SDO extension
you must add the following line to php.ini:

extension=sdo.so

For more information about building PECL packages, consult the
PECL installation
section of the manual.

Building SDO on Linux

This section describes how to build the SDO core and XML DAS on
Linux. You would only need to know how to do this if you wish to
build a recent version that you have checked out of SVN.

It is a shame they haven't upgraded this package. However, there is a update on github so that it will compile on php 5.3. Unfortunately it still doesn't compile on a Mac, because is uses a preprocessor macro (__WORDSIZE) which is not defined. I just assumed it to be 32b, and edited the code accordingly (using CloCkWeRX's branch).
